✦ Synopsis

Adsorption of anions on single crystal and polycrystalline silver surfaces has been monitored with optical second harmonic generation. Potentials investigated were restricted to the range between solvent reduction and the onset of metal osidation. Excess charge density on the metal surface is concluded to be a major factor in the voltage-dependent production of the harmonic light. The results demonstrate the potential of this method to measure ionic adsorption quantitatively at the interface.

Optical second-harmonic generation has been used to follow in situ the growth of thin Ag Ðlms deposited on Si(111) under various substrate conditions and temperatures. This method is particularly sensitive to the microscopic structure of the deposited Ag Ðlms. Thus, island formation is found to enha

The underpotential deposition of copper on (100) and (111) palladium single crystals and polycrystalline substrates was investigated voltammetrically. Charge values indicate that the adsorption process leads to the formation ofa first monolayer which follows the substrateorientation. On the (100) pl
